Customize welcome and invite emails

When you invite a user to join Sigma, they receive an email with a sign up link. Each user receives a welcome email after they create a Sigma account.

With email customization, organization admins can add their own content to two types of emails:

• Invite emails: When a user is invited to Sigma through Sigma’s invite modal, the default invite message will appear and the user sending the invite will have the opportunity to change the invite message from the default.
• Welcome emails: Every user who joins Sigma will get the Welcome email with the default message.

Some information that you might add to your default messages includes:

• How your organization is using Sigma
• What data is available in your cloud data warehouse
• Links to internal resources like a data dictionary or getting started guide
• Links to dashboards you think all users should know about
• Information on who to reach out to with questions about Sigma

Custom SMTP server

Configuring a Custom SMTP server lets you send Sigma emails from your own SMTP server. When you use your own SMTP server, Sigma-generated emails are sent from an email address within your domain. You can customize the branding of Sigma-generated emails, including the sender & reply-to address and sender name. The branding options provide the capacity for you to create a consistent user experience that enhances your organization's image.

Sigma can't monitor email deliverability if you configure your own SMTP server.

Custom SMTP also offers the following benefits:

• Email Deliverability: The ability to configure your email server settings, which are optimized for your org's email infrastructure, can improve email deliverability.
• Security Improvement: You control the security of all email data and communications. 
• Security Improvement: Consistent branding combined with a trusted sender increases security as end users can more easily identify phishing vs. authentic emails.
• Flexibility: Increases your flexibility & control over your email infrastructure. You can easily modify your email settings and troubleshoot issues as needed.
